6054fae2 · ·2023-08-10 v3.7.0 This release includes new codec interfaces, compression efficiency and perceptual improvements, speedup and memory optimizations and many bug fixes. This release is ABI compatible with the last release. - New Features * New codec controls: * AV1E_SET_QUANTIZER_ONE_PASS: Set quantizer for each frame. * AV1E_ENABLE_RATE_GUIDE_DELTAQ: enable the rate distribution guided delta quantization in all intra mode. The "enable-rate-guide-deltaq" option is added for this control. * AV1E_SET_RATE_DISTRIBUTION_INFO: set the input file for rate distribution used in all intra mode.
